Summary

Join me for an empowering conversation with Dr. Amy Killen, a board-certified emergency physician turned longevity expert, as we explore how women can thrive in their "Queen Phase"—the years following the loss of the protective "estrogen shield" . We dive deep into the nuances of Hormone Replacement Therapy, celebrating the recent FDA updates on estrogen and dispelling myths about testosterone for women . Dr. Killen breaks down the science of stem cells, explaining the difference between autologous (bone marrow/fat) and allogeneic sources, and shares vital red flags to watch for in regenerative clinics . We also discuss the critical link between mitochondrial health and sexual longevity, the potential of peptides like PT-141 and GHK-Cu, and why heavy lifting and sleep are non-negotiable for aging well .

Guest Information: Dr. Amy Killen is the Co-Founder of Humanaut Health and the founder of the Human Optimization Project. You can find her at https://biorestoration.com/dt_team/person-01/ and on Instagram @DrAmyBKillen .
